For a modern processor, "ICE" means something different than what you
are thinking of. NO one debugs with a true "ICE" any more, everyone uses
JTAG. JTAG debuggers are cheaper now:

is a commercial product that works with K8 series processors. It is $750.
You can see the coverage map at:

American Arium also sells ITP for lots of processors:

They don't have quotes on their website, but you can probably get one
for a couple of thousand dollars.
FS2 is the JTAG ICE supplier for Geode GX and LX, it is available for a
similar price.
Adding to Ron's homebrew stuff:

is a $35 board that very easily talks JTAG from USB.
